If it's important to you, I would suggest maybe approaching it from the other direction. (The *traditional* direction, in factit's frustrating when you're doing your best to try to be responsible about what you consume...when you can't even figure out where it's really made

Rather than "this is what I want, what brand/source shall I buy?", you can instead approach it as "I am looking around and here are the local-sustainable-whateverelseIcareabout things available to me, now how much variety can I generate from those ingredients".
You may well still choose to buy other ingredients from further away or more mysterious sources; but at least you will be buying as MUCH known-origin food as possible.
It may however necessitate cooking according to what you have on hand, rather than the modern habit of cooking according to whim.
